CORKSCREW.

erncrr'rcn'rioiv forming part of Letters Patent No. 299,738, dated June 3, 1884'.

Application filed January 17, 1883.

screw, and also to provide means by which the corkscrew can be used to cut the wires which secure the corks.

The invention is illustrated in the accompanying drawings, in which Figure 1 shows an elevation of the entire corkscrew. Fig. 2 shows a plan view of the handle of the corkscrew with the wire-cutting attachment; and Fig 3 is a sectional view of one of the wedgeshaped sides of the bridge on the dotted line 00 y, Fig. 1.

' Similar letters refer to similar parts throughout the several views.

A B is the screw, the upper part, A, having aleft-hand thread, and the lower part, B, which passes into the cork, having the ordinary righthand thread. The part A of the screw terminates at its upper end in a head, 0. The handle D of the corkscrew is made with a female screw, in whichthe male left-hand thread A works, and E is a bridge, which fits, by means of the collar F, upon the neck of the bottle. The upper part of the bridge E is formed into a sleeve, H, through which the screw A B slides freely. I and J are washers, which may be dispensed with or not, as de- The standards or sides a b of the bridge E are formed with sharp edges on their inner sides, which gradually converge toward the top of the bridge. The left-hand thread A is of such a length that the handle D, when screwed down upon it, will bottom before the handle touches the sleeve H, so that when the handle reaches the bottom of thethread a continued turning of the handle D ina left-hand direction will cause the thread B to unscrewfrom the cork.

The operation of the corkscrew is as follows (Model) The collar F and bridge Ehaving been placed in position upon the neck of the bottle, the handle D is screwed up to the head 0. The screw is then turned by means of the handle D, and the part B is screwed into the cork. The handle D is then turned in a reverse direction upon the left-hand thread Aby means of the knob Z until it engages with the top of the bridge E. A continued turning of the handle D then withdraws the screw from the bottle and the cork with it. The cork is subsequently disengaged from the screw by still further turning the handle D in aleft-hand direction, as the cork is held from turning by the sharp converging sides a I).

It is obvious that the sides or standards a b may be formed into other shapes which will hold the cork nearly or quite as well as the wedge shape shown. For instance, they may be formed like the letter U; but such modifications are merely matters of mechanical skill and judgment.

The construction of the wire-cutting attachment is shown at Fig. 2. One end of the handle D is formed with a longitudinal slit, e, in which is pivoted the blade f. The blade f is divided longitudinally to admit the wire of the cork, and the inner end of the longitudinal division terminates in a circular opening, it, having sharpened edges. Its operation is as follows: The blade f being placed as shown by the dotted lines, Fig. 2, the wire is introduced into the circular opening a. The blade f is then turned on its pivot and cuts the wire against the sides of the handle of the corkscrew after the manner of a shears.

I do not limit myself to the precise form of 2. The combination, in a corkscrew, of a screw having a left-hand and a righthand thread, a handle running upon said left-hand thread,'and a bridge with converging sides, and having its top formed into a sleeve, through which said screw passes, and its base terminating in a circular collar, all substantially as and for the purposes set forth.

3. The combination, in a corkscrew, of a screw having a left-hand and a right-hand thread, a handle running upon said left-hand thread, and a bridge with wedge-shaped converging sides and having its top formed into a sleeve, through which the screw passes, and its base terminating in a circular collar, all substantially as and for the purpose set forth.

4. The combination, in a corkscrew, of a screw having a left-hand and a right-hand thread, a handle running upon said left-hand thread and provided with a cutting-blade, and a bridge with converging sides and having its top formed into a sleeve, through which said screw passes, and its base terminating in a circular collar, all substantially as and for the purposes set forth.

5. The combination, in a corkscrew, of a screw having a left-hand and a right-hand thread, a handle running upon said left-hand thread and provided with a cutting-blade pivoted to said handle, and a bridge with wedgeshaped converging sides and having its top formed into a sleeve, through which said screw passes, and its base terminating in a circular collar, all substantially as set forth and described.

6. In a corkscrew, a handle with awirecutting blade, f, pivoted within a slotin said handle, substantially as set forth and described.

7. Ina corkscrew, a bridge having converging sides or standards, substantially as set forth and described.

8. In a corkscrew, the bridge E,with wedgeshaped converging sides a b, substantially as set forth and described.
